People must have certain personality traits and social resources, referred to as health literacy, to access, comprehend, and use the information to make health decisions. Patients' ability to manage complex diseases and care for themselves is strongly related to their level of health literacy. It can help us stay healthy by preventing illness and managing existing illnesses effectively. People with low health literacy (LHL) may struggle to manage their condition and prevent illness, leading to increased use of healthcare services. Furthermore, LHL is associated with more hospitalizations, elevated use of emergency care, decreased use of preventative services, and a decreased ability to understand labels and health messages, as well as a worsened state of health, higher mortality, and more expensive medical care.
